What problem does it solve? Turning raw screen captures and narration recordings into a finished demo video requires tedious manual timeline editing, and timing mismatches between clips and voiceover produce cut-off narration or dead air. This Skill reconciles measured media durations into a validated timeline and renders the final cut automatically. ## Core Features & Use Cases - Timeline reconciliation: Converts storyboard intent plus measured clip and audio durations into a frame-exact timeline.json, fitting clips with playback-rate adjustment, tail trimming, or last-frame holds. - Two finish paths: Renders headlessly with a bundled Remotion project (draft and final presets) or exports FCPXML for finishing in Final Cut Pro with MotionVFX titles and lower thirds. - Customizable studio: The bundled Remotion project supports theming, new section types, transitions, captions, and music ducking while preserving the measured timeline contract. - Use Case: After capturing UI walkthrough clips and recording narration, run reconcile and render to produce a draft MP4 for review, then export FCPXML when designed graphics and hand-tuned finishing in Final Cut Pro are needed. ## Quick Start Ask the assistant to reconcile the captured clips and narration in the current project and render a draft demo video for review.
